Since then i've noticed it majorly overheating (which is apparently an issue with others' s4's as well?) while just going through it sometimes, but significantly while it's plugged in and charging.
anyway, since that first day, i have now noticed the battery draining like 5-10% every hour even if i'm not using it. i've disabled absolutely every unnecessary app i could (including s voice), always have my brightness on the absolute lowest, and always have power saving on. like i'm looking at my battery usage now and i've been 58 mins on battery since the last charge to 100% and i'm down to 83%. all i've done is scroll through the app manager list a couple times to see if i missed anything else worth disabling.
I'd be interested to find out if others think the S4 gets hot. My Evo 3D gets super hot sometimes, especially when the radios are trying to find a signal and the battery is dropping. I can feel it just getting hot in my pocket, I need to pull the battery and reboot so it cools down.
I also notice when I talk on the phone the screen gets really warm against my face. Hoping the S4 doesn't experience similar symptoms.
One thing I've read is to make sure you are using a good charger. Cheap Chinese knock offs can deliver inconsistent voltage and can cause damage to batteries including shortening lifespan and sometimes even cause them to overheat and explode. This isn't to say all generic ones are bad, but more to illustrate the point that chargers can cause some battery issues and even be dangerous. I always figured a charger was a charger.
